Abstract
A cache server includes a media serving engine that is capable of distributing media content. A cache engine is coupled to the media serving engine and capable of caching media content. A set of cache policies is accessible by the cache engine to define the operation of the cache engine. The cache server can be configured to operate as either a cache server or an origin server. The cache server also includes a data communication interface coupled to the cache engine and the media serving engine to allow the cache engine to receive media content across a network and to allow the media serving engine to distribute media content across the network. The cache policies include policies for distributing media content from the media server, policies for handling cache misses, and policies for prefetching media content.
